Light path control member, display device including same, and method for manufacturing light path control member

A method for manufacturing a light path control member, the method comprising:

• disposing a first electrode on a first substrate;
• forming a light alignment polymer material layer on the first electrode;
• forming a plurality of openings from a surface of the light alignment polymer material layer;
• forming a high refractive part around the light alignment polymer material layer from the light alignment polymer material layer;
• disposing a transmittance variable part in the openings;
• disposing a second electrode on the transmittance variable part, the high refractive part, and the light alignment polymer material layer;
• and
• disposing a second substrate on the second electrode,
• wherein the transmittance variable part is disposed between the light alignment polymer material layer and the high reflective part,
• wherein light transmittance of the transmittance variable part is changed based on voltage.

A display device, comprising:

• a display panel;
• and
• a light path control member on the display panel,
• wherein the light path control member comprises:
• a first substrate;
• a first electrode disposed on the first substrate;
• a light conversion unit disposed on the first electrode, the light conversion unit including:
• a light transmitting part,
• a high reflective part around the light transmitting part, and
• a transmittance variable part between the light transmitting part and the high reflective part;
• a second electrode disposed on the light conversion unit;
• and
• a second substrate disposed on the second electrode,
• wherein light transmittance of the transmittance variable part is changed based on voltage.
